php_config.h for both a working and non-working configuration were sent
to sniper at php dot net. The difference between the two was:

I'm still waiting for the php_config.h from the build the test fails
with..
------------------------------------------------------------------------
[2006-01-03 22:48:28] jgmtfia at gmail dot com
When I use the configure line:
./configure --disable-all --disable-cgi --enable-debug
The test passes and the strace output looks very much like that of php
4.3.10-15.
write(1, "Checking A.\n", 12) = 12
access("A", F_OK) = 0
write(1, "Checking C.\n", 12) = 12
access("C", F_OK) = 0
write(1, "Unlinking C.\n", 13) = 13
unlink("C") = 0
write(1, "Checking C: ", 12) = 12
access("C", F_OK) = -1 ENOENT (No such file or directory)
Which is the expected output.
I also tried ./configure with no arguments, which worked. I then went
back to my original configure was:
./configure --with-apxs2=/usr/bin/apxs2 --enable-so \
--with-xsl --with-xmlreader
I have narrowed it down to the
--with-apxs2=/usr/bin/apxs2
flag.
When this ./configure flag is given the problem occurs in the cli
version of PHP. When this flag is not given the test passes.

Configure PHP with this configure line:
# rm config.cache ; ./configure --disable-all --disable-cgi
--enable-debug
# make
Then test, if it fails -> send your main/php_config.h to me.

I want to ensure that I have made my point clear. I have made a
simplier example, and have included an edited strace of PHP built from
yesterdays source.
The test:
<?php
`touch A; ln -s A C`;
echo "Checking A.\n";
if(!file_exists('A')){
echo "A does not exist.\n";
exit;
}
echo "Checking C.\n";
if(!file_exists('C')){
echo "C does not exist.\n";
exit;
}
echo "Unlinking C.\n";
unlink('C');
clearstatcache();
echo "Checking C: ";
if(file_exists('C'))
echo "(FAIL) exists\n";
?>
The ouput:
Checking A.
Checking C.
Unlinking C.
Checking C: (FAIL) exists
The edited strace:
write(1, "Checking A.\n", 12)
lstat64("/home", ...) = 0
lstat64("/home/user", ...) = 0
lstat64("/home/user/x", ...) = 0
lstat64("/home/user/x/A", ...) = 0
access("/home/user/x/A", F_OK) = 0
write(1, "Checking C.\n", 12)
lstat64("/home", ...) = 0
lstat64("/home/user", = 0
lstat64("/home/user/x", = 0
lstat64("/home/user/x/C", = 0
readlink("/home/user/x/C", "A", 4096) = 1
lstat64("/home/user/x/A", ...) = 0
access("/home/user/x/A", F_OK) = 0
write(1, "Unlinking C.\n", 13) = 13
unlink("/home/user/x/C") = 0
write(1, "Checking C: ", 12) = 12
***ERROR SHOULD BE "/home/user/x/C" BELOW ***
access("/home/user/x/A", F_OK) = 0
***END***
write(1, "(FAIL) exists\n", 14) = 14
So the question is why is PHP calling access("/home/user/x/A") when the
code calls file_exists('C')?
Also note that if the file_exists('C') call is removed from the start
code, the code then executes correctly.
<?php
`touch A; ln -s A C`;
echo "Unlinking C.\n";
unlink('C');
clearstatcache();
echo "Checking C: ";
if(file_exists('C'))
echo "(FAIL) exists\n";
?>
I don't know if it would be the operating system that would cause PHP
to access("/home/user/x/A") when I call file_exists('C').
debain php4.3.10-15 does pass the test and there are no lstat64 or
readlink calls.
write(1, "Checking A.\n", 12) = 12
access("A", F_OK) = 0
write(1, "Checking C.\n", 12) = 12
access("C", F_OK) = 0
write(1, "Unlinking C.\n", 13) = 13
unlink("C") = 0
write(1, "Checking C: ", 12) = 12
access("C", F_OK) = -1 ENOENT (No such file or directory)

You can strace the script and see what files are actually being
accessed.
